According to the latest statistics, from January to September 2006, the company's operating indicators hit a record high, and production and sales revenue exceeded last year's full year. Cumulative production and sales of 166,830 heavy-duty transmissions and 162,549 sets, an increase of 51.5% and 50%, and the market share of heavy-duty vehicles with more than 8 tons in China has increased from 72% to 75%, which has become a veritable "China's heavy-duty automotive transmission brand. ".

As the largest professional heavy-duty transmission manufacturer in China, Fast has created many firsts: China's first heavy-duty vehicle transmission, China's first heavy-duty transmission series, China’s heavy-duty vehicle transmission market share, China’s first A company that exports heavy-duty transmissions to the international market in bulk, and China's first enterprise to turn gear products into the supporting fields of international OEMs, ranked the first in the economic indicators of the Chinese gear industry, and the annual output of heavy-duty transmission year-end plants... ...

Overall design is scientific and reasonable

Fuel-efficient (high value-added), high attendance (reliability), convenient service (good after-sales service quality, and quick and prompt service) are three goals that Fast has established for all users.

In the mid-1980s, in order to accelerate the development of China's heavy-duty auto industry, Fast used its imported technology to produce China's first-generation double countershaft heavy-duty transmissions and quickly became the mainstream product of China's heavy-duty auto industry. With the rapid development of China’s heavy-duty auto industry and the continuous demand for new technologies and products, Fast has further accelerated the pace of independent innovation on the basis of the introduction of technology, digestion and absorption, and actively cultivates self-reliance based on China’s national conditions. R&D innovation capabilities. After many years of continuous technological innovation and technological transformation, nowadays, the twin countershaft transmissions developed by Fast, with independent intellectual property rights and high technology content, have reached more than 20 series and hundreds of varieties. All-around coverage is achieved in the 5 to 16-speed heavy-duty transmission field. It is widely used in various models with input torque ranging from 500 to 2,600 Nm and loads ranging from 5 to 50 tons. The transmission can be synchronized for each gear. Device. In particular, the 12- and 16-speed heavy-duty transmissions introduced in 2005 represented Fast's latest technologies and achievements. Among them, the creativity of some independent innovation products in key technologies and core technologies has filled the production gap of China's multi-range mechanical heavy-duty transmissions. It has been ahead of the international level, not only breaking the intellectual property barriers built by multinational companies, but also forming Scale development competitive advantage. According to the user's use effect and the analysis of experts, Fast Transmission has several core advantages:

The transmission is an important part of the chassis configuration of the car. Its technology and market trends are closely related to the development of the vehicle technology. At present, there are two main categories of mechanical transmissions for heavy-duty vehicles. One is a single countershaft transmission, and the other is a double countershaft transmission. The two types of transmissions have their own advantages in terms of structural performance. However, in practice, due to road conditions, load, and transportation, dual-shaft transmissions are more suitable for China's national conditions and are widely favored by Chinese users. The domestic transmission companies currently rely mainly on single countershaft transmissions, and Fast is the only company that is led by dual countershaft transmissions and supplemented by single countershaft transmissions. The advantages of high-, medium-, and low-grade heavy-duty transmissions complement each other. Enterprises, and to achieve product science, diversification, serialization, all-round development.

Fast double countershaft transmission is advanced in design and unique in structure. The power is input from the input shaft, then divided into two intermediate shafts, and finally converged on the main shaft output. This realizes the internal power splitting of the housing, thereby reducing the load on each intermediate shaft and each gear in the transmission by half, greatly improving The force conditions of the gears, bearings and housings make the width of the gears and the size of the assembly can be greatly reduced, which brings great convenience to the lightweight design of the products and the overall arrangement of various short-wheelbase heavy-duty vehicles.

In addition, the spindle of the main box adopts a hinged floating structure. The main shaft gear can float radially on the main shaft, canceling the needle roller bearings of all the gears on the main shaft, and reducing the transmission parts. The gear adopts a large arc tooth root and a quasi involute tooth design. The K-shaped block diagram according to the data design controls the tooth shape modification, improves the meshing condition of the gear pair, reduces the noise, and improves the bearing capacity.

In particular, in recent years, all new products developed by Fast have adopted the high-tooth finite element design, and the teeth have been designed as non-standard involute K-shaped teeth. The main and auxiliary boxes are equipped with high-performance double The cone synchronizer greatly improves the reliability and maneuverability of the product, and provides the best configuration for the upgrading of China's heavy trucks.

Fast double countershaft transmission has a wide range of applicability and good vehicle matching. The need for multiple functions of the vehicle has been fully taken into consideration during design, and the power-taking parts are numerous and convenient. Under normal circumstances, the rear power take-off device can be installed at the rear end of the auxiliary box countershaft, and various types of power take-off devices can be installed at the bottom, front and side of the transmission to meet the special requirements of all walks of life. It can be widely used in various road vehicles, dump trucks, tractors, military heavy-duty vehicles, truck cranes, large-scale fire engines, airport refuelling vehicles, concrete mixers, railway railcars and other special vehicles and special vehicles.

Energy saving and low cost of use

According to Deputy Chief Engineer of Fast Co., Ltd. and Wang Shunli, director of the Institute of Gear Research, the biggest highlight of Fast Transmission is energy saving, high reliability, and low cost of use.

In the same load capacity, the same road conditions and the same conditions of use, heavy-duty vehicles equipped with Fast 12-speed transmissions save 4 liters of fuel per 100 kilometers, greatly reducing the user's transportation costs.

"The selection of a tune-shift transmission is equivalent to a successful choice." This is a sigh sent by Shanxi user Wang Yonglin and Qian Liji who made a special trip to Xi'an to replace the Fast transmission. When the reporter conducted a telephone interview with him, his coal cart was driving on the Datong Highway. This is a professional coal transporter with more than 10 vehicles. He said: "Faster's gearbox is very compact, fuel-efficient, has good climbing ability, and has a low cost of use. Even if all the cars are out of service, the transmission will be ok. For more than ten years, I have been really affected by the selection of a steering wheel. Benefits, the cost savings are not a decimal. "Here now, he used the heavy truck trucks are all equipped with Fast transmission. Wang Yonglin spoke on the phone about the story of a Fast Transmission. He said: “The most feared heavy-duty truck is the start of a hill climb. The steep slopes of heavy-duty trucks equipped with Fast 12-speed transmission are not afraid. This October On the 3rd, due to the road conditions, all the coal trucks were forced to stop on a slope, and after the release, only my coal trucks could start quickly and win a cry.After returning, a lot of transporters were planning to change the taxis. Special 12-speed transmission.” According to Wang Chengwang, an ore transporter in Jixian County of Shanxi Province, a heavy-duty 350-horsepower heavy-duty truck equipped with a 12-speed transmission from Faste can increase the carrying capacity by about 25 tons, which is particularly effective in fuel economy. He used heavy trucks. All twelve-speed transmissions are currently installed on the transport vehicles.

Guo Peibin, a user of the North Mercedes-Benz 2542S heavy-duty motor vehicle, said: “In August this year, I chose the Fast 12-speed transmission. Compared with the original transmission, I found that I had a big advantage. I could save more than 200 yuan per kilometer of oil. The fuel economy is 4 liters per 100 kilometers.” In his words, “The 12-speed Transmission was selected to be installed. One year later, the cost of light oil was a matter of how much each car was not worth more than 20,000 yuan. Fast White sent a transmission."

Today, no one in the domestic and international heavy-duty auto industry knows Fast. In China, 75% of the users chose Fast heavy-duty transmission products, which undoubtedly corroborates the statement that “the selection of a tune-shift transmission is equivalent to a successful choice”.

At the beginning of 2002, user Cheng Xianghai brought his cash to come in for a three-time cash shift. At that time, he felt that "the quality of the transmission of the Fast was assured, with peace of mind and eager to serve." At the end of 2002, Cheng Xianghai was even more happy. Now as long as one phone call, Fast technical service personnel will come to the door 24 hours a day. In the words of Cheng Xianghai, "Faster is the 'Haier' in the transmission industry."

"Concerned about the user, family service, and super moving service" is the highest concept of Fast Service users. In the eyes of the Fast people, "the small things of the users are the big things of the company and must be solved within 24 hours."

In the winter of the previous year, Zhou Zhiping, a technical service technician from Fast, received a repair call from Shaanxi Auto's users and immediately rushed to the scene. On the ninth day of cold weather, for convenience, he was taking a high fever and took off his cotton clothes and drilled into a narrow space to begin repairs. He soon became cold and warped. The user distressedly said: "I don't have to fix it today, let's talk about it tomorrow." Zhou Zhiping said, "No, today I have to fix it for you. Otherwise, it will affect your business." The user's heart suddenly filled A warm current.

Before the Spring Festival in 2005, a busy one-year service technician appraisal officer of Falter Changchun Special Service Station bought a train ticket to go home. When it was ready to leave, a Yanji user called to repair the phone. The fault location was far away 500 kilometers away. , uninhabited. When Fan Shigang arrived at the scene, it was around 1:00 in the morning. In the temperature of minus 40 degrees, he immediately started the inspection and repair operations, and followed the service for nearly three hours. At this time, Fan Shigang's hands and feet were frozen and numb.
